Can you save him?

No. This was the sadest part for me. But he stated that he knew he would have to give up the secrets, and he also stated that he knew he would die in doing so. You can bet your bottom dollar his death did not go to waste.

Thank you. (I will be crying)

I did.

His death is scripted. Do you really think that Hermaeus Mora would be cheated of his rightful prey?

Still. It was very very touching

Absolutely. A powerful and tragic scene. I really did not want to play it through, having a dreadful suspicion of what was coming, but he chose his fate and met it nobly.

I made sure that his dead had a purpose. I killed Miraak, but I blame Hermy

...I knew going into it that Storn was going to eat it, but...I was kinda playing it as a follower of Hermaeus Mora...
I'm a Battle Mage...The promise and allure of forbidden knowledge and the power to bend others to my will was too strong.
In the end, I took my rightful place by my Masters side, and I would not be making the same mistakes Miraak did.

Storns sacrifice will not be forgotten as the one who gave those secrets in the writings of Apocrypha. Many more have suffered worse fates for less noble causes at the hands of Daedra.

When his daughter said "do something" i actually got out my warhammer and tried to kill him myself
